1798772 - In some cases, failing to delete empty 2nd-level subfolder in `Bin` (Trash) folder under Gmail's own folder list (IMAP)

Status: NEW

(Thunderbird :: Folder and Message Lists, defect)

+++ This bug was initially created as a clone of Bug #1752555 +++

Seen on TB 102.4.1 (64-bit), Win10.

This may either be a total edge case, or point to something wrong with our deletion mechanisms for Gmail, and we have a couple of reports on failing folder deletions.

STR

• Gmail IMAP account, select Bin folder of Gmail's own folder hierarchy.
• Create Subfolder1, and inside that, Subfolder2 (2nd-level subfolder)
• Copy a message from Google's Important folder (below Bin in the Google folder) (sic, this step makes the difference)
• Select the message, then select Subfolder2 (2nd-level subfolder inside special Bin folder, this matters) - message is now grey-selected, Subfolder2 is blue-selected
• Press Del key two times

Actual

• first Del deletes message (OK - by design, we prefer deleting the selected msg first even though folder has focus, ux-error-prevention)
• next Del asks to delete folder, and fails with error message from server, now impossible to delete folder

Expected

• Should be able to delete the folder

Sorry, I can't spend time to reproduce this further, and changing most parameters seems to work around the bug.
